Have tried most all of them, each has strengths and weak points. Phoeinx has been far and away the best for me. Thing I liked best was it focused on RC skills and not 'gaming'. I really dont care what my flying looks like from the cockpit or flying planes that I'll never have. Anyway, using it when starting out resulted in a HUGE improvement with items like landing, recovery from unusual attitudes, etc.. Nowadays I use it to practice and keep the thumbs current during seasons of limited flying.
